Specification forming part of Letters PaientNo .15l .,150, dated-January 26, 1875; application filed 7,

July 18, 1874.

To all whom it may concern i Be it known that I, GEORGE F. BRINKER' HOFF, of Bucyrus, in the county of Crawiord and State of Ohio, have invented a new and valuable Improvement in Collar and Thimble for Stove-Pipes; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings making a part of this specification, and to the" letters and figures of reference marked thereon.

Figure 1 of the drawing is a representation of a sectional View of my collar and thiinble.

Fig. 2 is a front View of the same. Fig. 3 is a perspective View of my improved thinihle, showing the manner of turning in the strips or branches; and Fig. at is an end iew of the said thinibie with alternate strips turned back against the inner wall of a flue.

This invention has relation to means for rigidly securing into the pipe-hole in the inner wall ofa fiuea thinible; and the novelty consists in a flange upon the inner end of the said thirnhle, preventing it from being pushed through the pipe-hole, and in branches out from the other end, which are bent alternately inward around the outer end of a stove-pipe inserted into the said thimble, and outwardly against the wall of the line, whereby the said thiinble is prevented from being withdrawn from thesaid pipe-hole, and the pipe is prevented from penetrating through the pipehole It also consists in a collar applied aroundthe pipe-hole of a flue upon the inside of tin-apartment, having a fiangeto' receive the flange upon the thinible, which collar is embedded into the plastering in new houses, or is secured thereon in old houses, on using a neat and appropriate appear ance to be given to the joint.

In the annexed drawings, A designates a chimney, into which a pipe is passed through the wall of a r-ooni'bounding the said line, in the usual well-known manner. 13 designates a collar of wood, metal, or any other suitable material, having a flange, b, and a circular bead, Z7, raised around its central peribration, the diameter of which is somewhat greater than the diameter of the pipe to he used. This collar is applied, when used with houses in pro- ,1 not only have in the plastering; but it may he put upon the plastering either in new or old houses, de-' sired. 0 designates a thinihle of sheet metal,- I

preferably of cylindrical form, upon the front end of which a flange, e, is made, its rear end being cut into a suitable number of strips or branches, 0 (2, in the length of the thiinble. It, now, the thinihle 0 be iii erted into the pipe hole, its branched end foremost, the flange a will shoulder against the inner flange, Mot the collar B, and will prevent it from hein g pushed into the flue and falling to its hottorn-an event which is not of iniiier'pient eeeurrencewith other thimbles. The hand is new inserted through the tliiinele late the line, and every alternate strip c bent radially down against the wall. of the ilue, as shown in Figs, 3 and 4,

causingthe thinihle to he rigidly helt'i'against falling inward into the room and covering and soiling ever thing with which it comes in eontaet. .l) indicates a section of a stove-pipe of the usual construction, which is inserted into the thiinhle until its inner edge is flush. with. the inner wall of the due. The remaining :3 tips (Z are then bent over and inward upon the iuner surface of ti-J pipesect on D 1d are torch bly flattened. lillGl'Ct'ill, thus pro ding hooks, which prevent it from penetrating too far into the Line and choking or impeding the draft. in designates a hook, which is secured at one of its ends to the collar lb, or to the wall of the apartment, and by the other to the pipe-sec tion, and which prevents itl'roui falling'inward into the room. I

It will be seen from the :iheve description that neither the thin hle nor the rupe -section can be thrust into the body of. the fine or caused to fall into the room, and that, in consequence, oided chokin up the hue, but also the disw -reeahle consequences entailed by the falling ct soutcovorcd thimhles and see tions of pipe into the room; also, that, by using a collar which may he ot' any desired degree of ornainentation, 1 intro converted a usually unsightlypart of a wall into one which will please the eye and add greatly to the appearance of the room. 4

The circular head l) of the collar 13 being of somewhat greater diameter than the pipe'section E, a space is left between it and the pipe,

which I preferably fill with cement, plaster-oi .paris, or other suitable compound, and thus prevent any escape Whatever of gas or smoke i ntotherooni, thereby efi'eetuall y prevent ng the deposit of soot upon the collar or upon the 'Walls of the room.

I am aware that a collar, a thimble, and a pipe-section are not new, and therefore I do a flange, I), and ahead, I), the thimhle 0,112?- ing a flange, c, and fastening-strips c d, and the pipe-section D, substantially as specified.

2. The thimble C, having upon one end a flange, c, and upon its other end fasteningstrips 0 d, substantially as sFecified.

In testimony that I claim he above, I have hereunto subscribed my name in the presence of two witnesses.
